IBU Calculator

Hops add bitterness to balance the sweetness of the sugars in from the malt. This calculator
with help you approximate bitterness in International Bittering Units (IBU) provided by your
combination of hops.

This means extract brewers which use smaller boils will need more hops to get
the same IBUs. There are some smaller adjustments we make in the utilization when
the hops are addded to the mash or the first wort. Dry hopping does not add any
bitterness to the beer but it does add aroma.
